wordwrap
将字符串以列宽（缺省为80）换行。作为可选的第二个参数，可以指定文本字符串用来将原来的文本换行，缺省是用回车"\n"。
缺省时，换行会尝试进行在单词边界处。如果你想精确的切断在字符长度处，可以设置第三个可选参数为TRUE。等于PHP的wordwrap()函数。
例子5-23. wordwrap
<?php
$smarty->assign('articleTitle',
"Blind woman gets new kidney from dad she hasn't seen in years."
);
?>

{$articleTitle}
{$articleTitle|wordwrap:30}
{$articleTitle|wordwrap:20}
{$articleTitle|wordwrap:30:"<br />\n"}
